Bosch M pump timing question
Bosch M pump timing question
Unburnt fuel means it'll be too retarded. Honestly the best way is just to move it around until it feels right. That's how I've timed my 7.5mm pump, have no clue how of the degrees but it seems happy...
With fatter elements you'll be injecting fuel faster, so it doesn't need to be as advanced as with a stock pump. In theory...
